Microchip Technology, Inc. Memory 25LC020A-H/SN

The 25LC020A-H/SN is a 2K-bit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Quarktwin Technology Ltd., designed for use in high-temperature environments with an operational range of -40¬8C to +150¬8C. It supports a maximum clock speed of 5 MHz and operates on a supply voltage range of 2.5V to 5.5V. The memory is organized in a 256 x 8-bit configuration and allows for both byte and page-level write operations, with a maximum write cycle time of 6 ms. This device features built-in write protection mechanisms, including a write-protect pin and power-on/off data protection circuitry. It also offers block write protection options, allowing users to protect none, 1/4, 1/2, or the entire memory array. The 25LC020A-H/SN boasts high reliability with an endurance of over 1 million erase/write cycles and data retention exceeding 200 years. The package is Pb-free and compliant with RoHS standards, making it suitable for environmentally conscious applications.
